Don't know if it's needed but it's on my to do list. Not really liking the way my stock SS handles thru the twisting roads near my house. Can't wait to get some suspension upgrades and a strut tower brace. So for me it's a (needed) item.

If you are going to be attacking corners then yes. I've always added a strut tower brace along with sub frame connectors,sway bars, and suspension so I've never really found out for myself how effective the tower brace is on its own but it certainly isn't a waste of money to have one. Your car is going to flex when you carry plenty of speed into a turn and you'll want as much precision as you can get.
